Organophosphates are used as insecticides, medications, and nerve agents. Because of these studies, dichlorvos is possibly carcinogenic to humans. Dichlorvos was restricted for use in Sweden due to its mutagenic properties (Reference 3). While the LC 50 for inhibiting mammalian brain acetylcholinesterase is similar between dichlorvos and paraoxon (i.e., the active metabolite of parathion), the acute LD 50 values for these agents are considerably different, due in part to the more rapid metabolism and elimination of dichlorvos. There is thus a real situation where a human may get exposed to these toxicants while working in a field. Dichlorvos was nominated for review under the Australian Pesticides and Veterinary Medicines Authority’s (APVMA) Chemical Review Program (CRP) because of its high acute toxicity and concerns over its carcinogenic potential.
